Which component is NOT part of the visual screening for second graders?

The correct answer indicates that the color vision test is not typically included as part of the standard visual screening for second graders. In general practice, visual screenings for this age group focus primarily on essential components that assess a child's ability to see clearly and function effectively in a classroom setting. This typically includes tests for visual acuity, which measures how well children can see at a distance, and evaluation through observation to assess any additional concerns regarding their visual behaviors.

Testing for far phoria is another common aspect of visual screenings, as it helps identify issues with eye alignment that may affect a child's ability to focus on objects at a distance. However, color vision is generally not a routine part of screenings for second graders because it is usually assessed only when there is a specific reason to suspect a color vision deficiency or if it is necessary for certain educational or vocational paths.

In summary, the focus during routine visual screenings for second graders revolves around determining visual acuity and general visual function, rather than testing for color vision, making this the correct answer.
